I took my M&P 15-22 out on the range today and the rifle started to have failure to feed issues from the first clip. I would pull the clip out and find the round facing straight up. This time I used CCI Mini-Mag (1260 FPS). I also tired the Federal's and had the same problem. The only things I can think of thats causing the problems is the weather. It was between 15-20 F on the range. Also the gun was a bit dirty, I put 400+ rounds through it the last time and didn't clean it. So what should I do? It's going to be too cold to visit the range for awhile so I am thinking of contacting S&W for shipping material and having them look at it. If it wasn't for all the **** going on in my life right now I might be more upset but I just don't have the time for it. Suggestions? Thanks.
